"Tons of problems"...strixowl, upgrade from Poser 3 and you might see some of those go away. Pardon the sarcasm but "tons of problems" is a little over the top in itself. P6 is the most stable Poser has been. With the addition of the SR1, it's a solid functioning CG program that is a reliable part of the creative toolbox. D/S on the other hand is more promises than deliveries. Imho its not yet capable of playing serious ball when it comes to creative realization. Not to say it won't be someday but as of now, its not yet there. I've used them both, and imho D/S is more of a time waster.
